The interaction between an acoustic wave and a complex media has an increase interest for nondestructive testing (NDT) applications. For specific applications using nonlinear imaging, inversion procedure needs specific signal processing techniques and new coding schemes. The purpose of this paper is to present the extension of TR-NEWS (Time Reversal based Nonlinear Elastic Wave Spectroscopy) methods for skin ageing characterization.
